Under certain circumstances, there is a risk that St. John’s wort will not survive the winter without damage. For example, freshly planted specimens in harsh locations and species from originally warm regions can suffer frostbite.
Protect endangered specimens
Basically, you do not need to overwinter your St. John’s wort. Most species, such as St. John’s wort, cushion St. John’s wort, beautiful St. John’s wort and mountain St. John’s wort, are hardy well. But sensitive species and those that are in a container or a harsh location should be overwintered.
Here’s what you should keep in mind when wintering St. John’s wort:
cut back before wintering
cover with leaves, brushwood or a layer of compost
Wrap potted plants with jute or fleece and place them against the protective house wall
Tips
Be sure to water St. John’s herbs in containers sparingly from time to time during the winter so they don’t dry out completely! However, you should take care that excess water can drain away easily.
